EZT-570S User Manual

6. Security
The EZT-570S security model provides an administrator with the tools to add up to 30 users to the
system. Each user must have a unique ID, full name and password. Four user levels are provided
which include system, user, supervisor and administrator levels. Specific access rights can be
assigned to each user level and password aging can be implemented. Verification is provided (if
enabled) for any parameters that will change a control parameter, which could upset the process (i.e.
loop set point, start/stop automated ramp/soak programs, etc).
Verification requires that the logged in user must log in again before the process value will actually be
changed. This feature is provided for extra security. The following example will make verification
clearer:
A supervisor logs on the system. The supervisor then steps away from the system to take a phone
call but does not log out before leaving. If another user tries to change the temperature control set
point, the system will require another login (by an authorized user for that level) before the control set
point is actually changed. This provides an extra level of protection to make the system more “tamper
proof”.
The ‘Security’ menu, accessed from the home menu, provides access to the security section of the
EZT-570S.
